I want to know what you think were the saddest moments of Call of Duty. If you don't think they're are that much, how would you make a sad, tragic Call of Duty moment. Just anything that has ever happened in Call of Duty even Multiplayer.
Single Player: Any moment where an NPC (Random one) who has stayed with you through the entire level then just get shot. It's sad because you thought they were going to make it.
Multi player: When me and a friend hold a house from enemies and just before the game ends he gets killed by a grenade.
